IMPROVEMENT IN CARDS FOR CARDlNG-MACHINES.

Specification forming part of Letters Patent N0. 54,270, dated April 24, 1866.

To all whom 'it may concern:

Be it known that we, WILLIAM TURNER and SAMUEL SHORE, of Tunnicliffe Mill, near Rochdale, in the county of Lancaster, England, and WILLIAM HALLIWELL, of Rochdale aforesaid, have invented new and useful lmprovements in Cards used in Garding-Engines and other Similar Machinery; and we do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, Which said drawings constitute part of this specification, and represen t, in-

Figure 1, a cross-section of a strip, showing four teeth, represented in black, the leather in red; Fig. 2, a View of the back of a strip, the teeth set as in clearer card or stapler card 3 and in Fig. 3, a like View, the teeth set as in fancy card.

This invention relates to the teeth of the cards; and it consists in making the teeth ol' different len gths, instead of one uniform length,

' as hitherto adopted. At present the wire is bent so as to enable the two prongs to project the same distance from the leather or band 5 lout we bend the wires so as to make one leg or prong longer than the other, and when the wires are passed throu gh the leather or band the teeth or pins are ot' different lengths, as seen in Fig. 1, and thus we form cards which, being of uneven surfaces, card, comb, and open brous materials much more efficiently than vthe ordinary cards. This system of having one prong longer than the other is applicable to stapler-cards as well as tooth-cards, and in any case it dispenses with the grinding of the teeth and prevents to a great extent the formation and collectionof waste.

When the teeth are set as seen in Fig. 2

(stapler or clearer) the points will appear in We do not broadly claim an irregular or uneven surface upon the face of the card, as

this is not new, such being found in the English patent of Daniels, specification No. 5,504, and dated' December 8, 1827.

We claim- In tooth and stapler cards used in cardingmachines, the system of making the prongs or legs of each staple or tooth of different lengths.

In witness whereof we, the said WILLIAM TURNER, SAMUEL SHORE, and WILLIAM HAL- LIWELL, have hereunto set our hands the 7th day of December, in the year of our Lord 1865.

WM. TURNER.

SAMUEL SHORE.
